  • How reduce the copper and iron losses of transformer?

    ​1. Choosing a lower current density and reducing the number of turns will increase the magnetic flux density of the iron core and increase iron loss.

  • What is the purpose of the motor winding resistance test?

    The main purpose of the motor winding resistance test is to ensure the normal operation and safety of the motor. This test checks whether the electrical connection of the winding is good by measuring the resistance value of the winding inside the motor.

  • Transformer DC resistance tester maintenance skills

    According to the division of labor of the management personnel in Taiwan, in addition to regular transformer work.

  • What is the difference between a shorted and open transformer?

    An electrical device called a transformer is used to move electrical energy between circuits. When there is a low-impedance channel between the transformer's primary and secondary windings, the transformer is shorted. An open transformer, on the other hand, happens when there is a high impedance or an open circuit between the transformer's main and secondary windings.

  • Inspection and identification methods for transformer on-load tap changer (OLTC) faults

    According to statistics, the faults of the on-load voltage regulating switch of the transformer mainly include two aspects: First, the failure of the voltage regulating switch driving mechanism, mainly including the linkage of the electric mechanism, water intrusion into the box, oil leakage from the gear box, insufficient spring energy storage, etc. The second is the failure of the switch body, which mainly includes oil leakage from the oil chamber, loose fasteners, stuck contact motion, and poor contact caused by contact wear. The common fault types of on-load voltage regulating switches are listed and analyzed below.

  • The principle and significance of testing methods for grounding resistance in substations

    ​In recent years, many substations in China have experienced expanded accidents due to lightning strikes. Most of the grounding resistance related to the grounding grid is unqualified, which plays a role in working grounding and protective grounding. When the grounding resistance is too high, a grounding fault occurs, and the neutral point voltage offset increases, which may cause the sound phase and neutral point voltage to be too high, leading to equipment damage and exceeding the required insulation level.
